Energy Use Analysis and Efficiency Improvements at Beloit College Campus

This report by Beloit College Sustainability Fellows, Grace Kellogg ('13) and Sierra Anseeuw ('11), focuses on optimizing energy use through the Weatherization Assistance Program (WAP). It highlights potential areas for energy savings, employing an economic model based on real price and energy use data. The model assesses the impact of insulation retrofits, calculating payback periods, net present values, and internal rates of return. Results indicate a significant reduction in heat loss, demonstrating effective insulation strategies such as blown cellulose and fiberglass batts.

  1. Energy Use on the Beloit College Campus Grace Kellogg, ’13, and Sierra Anseeuw, ‘11, Beloit College Sustainability Fellows Program • Analysis of Weatherization Assistance Program (WAP) highlights areas of potential energy savings. We created an economic model which used actual • From Energy Audits to Economic Analysis: • price and energy use data to calculate the savings accumulated by the addition of insulation, payback • period, net present value, discount rate, and internal rate of return. The model can be modified for a variety of energy saving retrofits.  Percent of heat lost through various components of the Human Resources House before the retrofit Percent of heat lost through the various components of the Human Resources House after the retrofit. Heat loss is 54% less. 26% 49% http://mayhem-chaos.net/ Blown cellulose is a good insulator in both attics and walls. http://www.savenrg.com/ Fiberglass batts save space and have high R-values. http://www.patdrake.ca http://www.greenmountaininsulation.com/
